Servlet using NES 3.5.1 and WLS 5.1

          Hello All!
          When I send the attached servlet directly to WLS 5.1 as Web-server it works fine.
          But when I use NES 3.5.1 as a Web-Server I receive the message:
          "Your client is not allowed to access the requested object."
          How can I solve this problem?
          Thanks for any help!

          try to access to your admin page only
          see if you get the same error if so
          Comment out "Hosts" and "Addresses" lines in the admin-serv/config/ns-admin.conf
          or change the value to *

How to compile and run a Java servlet using the BEA weblogic server

          Hi,
          Could you help me out as to how to compile a servlet using Web Logic server.I have written a Servlet program and have also set up the environment in the "c:\bea\wlserver6.0\config\examples" folder by giving the command setExamplesEnv.cmd.
          I have stored my GreetingServlet.java file in "c:\bea\wlserver6.0\samples\examples\servlets" folder.
          How do I compile my servlet now?
          Vid


Hello,
1. The .form file was used by Netbean's GUI builder to create the .java and is not needed for compilation.
2..../src # javac -classpath "..." mytool/*.java
I guess the package mytool was not coped with.
Alternatively it is worth to use the ant build tool also used by Netbeans.
Then you can make a jar from the class files, indicate in the manifest.mf file:
1. the main class
2. the library jars

How to run jsp and servlet using JBOSS server

Dear Friend,
I have JBoss application server and Eclipse id
now i want to run JSP and Servlet but i am not getting the place where to place my servlet class file to run it .
before that i run jsp and servlet using tomcat5.0 but in that i place my servlet class in WEB-INF/classes folder and do corresponding entry in web.xml file and run it through browser.
now i want to use JBOSS how it is possible
PLZ Help me

Is the servlet class defined in a package.? If servlet class package is servlets., copy the servlet to
WEB-INF/classes/servlets directory.

Accessing servlets using login and goto

Hi,
I'm having a problem in accessing servlets without visiting the DesktopServlet. There is no problem if the servlet does not require a parameter, but if I try to pass a parameter to the servlet, it does not pass the parameter -
Without visiting the DesktopServlet when I try to visit an servlet X , it gives me a session exception.
Thrown SessionException : Invalid service host name.
I use the following code to login and go to the servlet :
String redirectTarget = "login?&goto=" + req.getRequestURI() + "&hotelComponent=" + hotelComponent;
resp.sendRedirect(redirectTarget);
Inside the doGet of the servlet, I now try to read the hotelComponent parameter -
String hotelComponent = req.getParameter("hotelComponent");
But now I get a null. I can not get the hotelComponent parameter. Any suggestions will be very helpful
Thanks in advance
Partha

Thanks for the suggestions ! The original problem of not being able to pass parameters like -
"login?&goto=" + req.getRequestURI + "?param=" + value"
has been solved by encoding the URL string sent to resp.sendRedirect.
However the suggestion you have given regarding setting of cookies in the browser might have a bearing on my actual problem. I'm trying to do away with the redirection to the login servlet in the DesktopServlet.
Here is what I'm trying to do to make our website searchengine friendly - using WGET scrape the DesktopServlet and set it as the index.html. When somebody tries to access the links which are ordinary servlets, it gives a session exception. I catch the session exception and in the catch block use "login?&goto" to do a response.sendRedirect. This does a login and gets me the session.
All the servlets work fine except for one which is identical to the ones working except for the fact it is a post from a form on the DesktopServlet. Here I get a HTTP 400 Bad Request error. I've noticed that when I clear the cache and try I get a better response.
Any suggestion on how to overcome this ( possibly by setting cookies ) would be greatly appreciated.
Thanks in advance

Load Balancing and WLS primary server offset

I've got a load balancer in front of my WLS cluster, and I'm trying to
          set up load balancing based on WLS clustering. What I need to know to
          do this is the offset within the cookie that's responsible for
          determining which machine within the cluster to direct to.
          Any idea how I can get this information?
          thanks,
          cfraser

          In Memory session replication doesn't work without our plugins. I will have to
          do little bit of investigation to figure out if other persistence mechanism's
          would work without our plugins if you are interested in them. I have to remind
          you though that other types of persistence mechanism's we support are slower
          compared to in memory session replication.

          Currently none. We are taking steps to make the plugin's and cluster more
          robust, we currently don't have any plans to work with other 3rd party vendors.

          This information is saved in the cookie. But I wouldn't count that, as we
          have plans to change this. I cannot give your more details.

          I don't quite get what you mean here.

Configuration with Tomcat, Firewall and WLS 5.1

Hi all,
          I have been reading the cluster documentation for WLS 5.1, but I can't
          find any information about a cofiguration which looks like (Top of list
          is the 'front'):
          Router
          (Some kind of load balancer)
          Cluster of Apache and Tomcat servers
          Firewall
          Cluster of WLS 5.1 servers
          Database
          To me it looks like all the configurations in the documentation use WLS
          to handle dynamic content (Servlets/Jsp).
          We will use Tomcat as Servlet/Jsp runner, and or not interested in using
          WLS for such things...
          WLS will be used as an EJB container, and we aren't using any statefull
          beans.
          So I have a few questions regarding the configuration above:
          1. Do we need to run the proxy plug-in in the web layer?
          2. Can we have a firewall between the web layer and the WLS cluster?
          3. How should the JSP pages choose a WLS server? Should we write some
          kind of proxy plug-in for Tomcat?
          Best regards
          /Kaj

          I've seen:
          Router
          Firewall
          (Some kind of load balancer)
          Group of Apache proxies
          Cluster of WLS 5.1 servers

          That's possible. I'd suggest anything but Tomcat though ... it's slow as
          mud. Check out Caucho Resin.
          > 1. Do we need to run the proxy plug-in in the web layer?
          No. The proxy is for proxying Http requests. Instead you will be looking
          up EJBs and getting cluster-aware stubs from Weblogic.
          > 2. Can we have a firewall between the web layer and the WLS cluster?
          Yes. But that means that there will be some way for systems other than your
          JSP/Servlet servers from accessing your EJBs. (Remember, if your
          JSP/Servlet servers have a way to poke through the firewall, then
          theoretically so does everyone else.)
          Instead, consider a simple port forwarding system. Close everything but 80
          and 443 and forward those to your load balancers and then on to your
          Apaches. To have redundancy on your firewalls, reverse the order of load
          balancer and firewall.
          > 3. How should the JSP pages choose a WLS server? Should we write some
          > kind of proxy plug-in for Tomcat?
          I believe that is the job of the cluster-aware EJB home stub.

Unable to deploy a simple servlet using WAR file on Oracle9iAS v9.0.3

Hi All,
I am facing problem while deploying a simple servlet using WAR file on Oracle 9i App Server.
I have installed Oracle9iAS J2EE and Web Cache v9.0.3 on Windows 2000 server.
It includes:
     - Oracle HTTP Server
     - Oracle9iAS Containers for J2EE
     - Oracle9iAS Web Cache
     - Oracle Enterprise Manager
The release of installed Oracle9iAS is Release 2 (9.0.3)
I referred following link to Deploy Applications Using WAR file:
     http://otn.oracle.com/products/ias/daily/sept12.html
As mentioned in this documentation I have followed following steps to deploy WAR file:
1] I have created a war file by name SimpleServlet.war. In SimpleServlet.war, there is a servlet by name Simple which prints time at which servlet was accessed.
2] I have modified <ora9ias_home>\j2ee\home\config\application.xml and added following web module entry:
     <web-module id="SimpleServlet" path="../../home/applications/SimpleServlet.war" />
3] To make this module accessible from over the web, I have modified file
     <ora9ias_home>\j2ee\home\config\default-web-site.xml and added following entry:
     <web-app application="SimpleServlet" name="SimpleServlet" root="/SimpleServlet"/>
4] I saved both the files and started Oracle HTTP Server and accessed page as below:
          http://<server>:7777/SimpleServlet/Simple
where Simple is servlet in SimpleServlet.war file.
In the browser, The page cannot be found is shown to user. I have verified that SimpleServlet.war is extracted to SimpleServlet folder under <ora9ias_home>\j2ee\home\applications folder. I found that Simple.class is stored under WEB-INF/classes folder and web.xml contains correct entry for url pattern for servlet Simple.
What else could be the problem? Am I placing the war file in wrong place or modifying application.xml or default-web-site.xml in a wrong directory?
This is very urgent. Please help me with your valuable comments on this.
Thanks in advance.

Sandesh

SandeshHave you restarted you http server and then tried to load it again? Are you using the right port; maybe you have to use port 7778? Check you server settings in the http server instance. Also check your url binding of you application at Farm > Application Server: infrastructurehost > OC4J_instance > Application: appname > Web Module: modulename
Good luck!

Servlets/JDBC - Connect to database ONCE and not in every servlet - How?

Hello, I'm using servlets and JDBC.
In every servlet , i connect to the database and then i close the connection, but this is not ptactical.
I would like to connect to the database once (at the beginning) when container starts and then close the connection.
How am i supposed to do that?
Thanks, in advance!

Bad idea. Don't do that. The connection will timeout sooner or later (depends on DB used, it's usually around 30 mins) and your application will crash.
You should always acquire and close the connection (and statement and resultset!) in the shortest possible scope. To improve connecting performance just use connection pooling.
Create a DAO class which does all the task and just instantiate and assign it as Servlet class variable during Servlet's init() method. For more insights and code samples start here: [http://balusc.blogspot.com/2008/07/dao-tutorial-data-layer.html].
To go back to your fundamental question, doing some stuff during startup and shutdown of webapp, you could use the ServletContextListener for this. But again, do NOT do this to get hold of an external resource such as a connection! It's receipt for trouble.

Problem to connect to mysql from servlet using a javabean

Hi,
I'm new here and beginner on java to.
I have problem to connect to MySql database, by a connection javabean.
It's the following: a HTML page calls a servlet and this servlet imports the package connection javabean.
It has no problem when I establish the connection inside the servlet, with all its methods (public and private). But i want to separate the code connection from servlet.
Detail: there is no problem, using the javabean to connect to MS Access database.
I put "mysql-connector-java-3.1.12-bin.jar" file inside WEB-INF/lib application and common/lib directories.
I set the classpath:
SET CLASSPATH=%CATALINA_HOME%\COMMON\LIB\mysql-connector-java-3.1.12-bin.jar;%CLASSPATH%
I think that the servlet cannot create an instance of javabean, because passed by catch exception of the servlet init method.
But I don't know why.
Please Why?
Below there are the fragment of errors, servlet code e javabean code.
Thank you.

I put "mysql-connector-java-3.1.12-bin.jar" file inside WEB-INF/lib application and common/lib directories.
I set the classpath:
SET CLASSPATH=%CATALINA_HOME%\COMMON\LIB\mysql-connector-java-3.1.12-bin.jar;%CLASSPATH%
I think that the servlet cannot create an instance of javabean, because passed by catch exception of the servlet init method.
But I don't know why.
Please Why?
Below there are the fragment of errors, servlet code e javabean code.
Thank you.
Zovao.

How to test servlet using Junit test????

Hello everybody
Does anybody know how to test an servlet class using Junit without using Cactus test . Is it possible to test a servlet using Junit without cactus test.Plz tell me the process how to test a servlet using Junit test .
Regards
srikant

1) Do yoiu mean how to "run" your servlet code with sample parameter? This call manual testing with a sample run of you code. You need a web server(eg Tomcat), create a webapp with your servlet then deploy it there in order to run it.
2) httpunit and junit are framework to write test case code that can be automated and repeatable. Plz read their doc.
3) Your sample code me a very wrong way to retrieve and convert servlet parameters.
Get a java toturial and servlet tutorial book and read it over the weekend. You need to get at least the basic.

Connecting a servlet using a midlet

Hi,
I am trying to connect to a servlet using a Midlet. The servlet is running fine on Apache Tomcat and I m able to build the MIDlet using J2MEWTK . But when I execute the Midlet on an emulator it shows me some code of html page of which the important line which might give u some hint is :
the requested resource (/hitservlet) is not available.
I wrote the code of HitServlet and Hitmidlet using a pdf on net....Do I need to install something else for executing this? I dont understand where is the problem. Should I post the codes? Is it something related to aliases...as indicated by some some tutorial...if so plss elaborate on it..
If anybdy has any idea ...plss help me get out of this problem...
Thanx
Smeeta

Have you added the URL of the Servlet into the J2ME application?
Settings -> UserDefined Tab
Thinks its
HitMIDlet.URL and its value should be the URL of the Servlet

When to use doGet(...) and when to use doPost(..)

Hi,
here is what i would like to do:
I have a html file that will take user input and pass these inputs to a servlet as parameters. the servlet then uses these input parameters to query for data in a database and then write this results back to the browser. Here is my problem:
If I use doGet(...) and hardcode the input parameters instead of taking them from the html file, I then can compile and run it from Jdev IDE. And if I use doPost(..) instead, I can only compile the servlet, but when run, I got the error message :
"The page cannot be displayed
The page you are looking for cannot be displayed because the address is incorrect."
To my understanding, please correct me if I am wrong,we use doPost() to accept pararmeters from a html. Please help me. thank you very much.
Tran T.
codes are as below:
<HTML>
<HEAD><TITLE>Session Payment Status</TITLE></HEAD>
<BODY>
<FORM ACTION="http://localhost:8080/servlet/SessionPaymentStatus" TARGET="FRA2" METHOD="POST">
<CENTER><H1><FONT COLOR="GREEN" SIZE="5"> Session Payment Status</FONT></H1></CENTER>
</HTML>
And my servlet is:
package paymentstatus;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import gmstocms.*;
import java.util.*;
import com.gaexpress.javaadapter.*;
public class PaymentStatus extends HttpServlet {
//CMS Related
private String xmlRecord = null;
private String storedProc = null;
private String ID = null;
private CmsXmlParser parsedRecord = null;
private Vector vecData = null;
//Record Header
String RecordID = null;
public void init(){
this.storedProc = "OLEDB$GETSESS";
this.ID = "CE97607";
public String getCMSRecord(){
//xmlRecord = new String (CMSTest.executeSP("OLEDB$GETSESS","CE97465"));
return new String (CMSTest.executeSP(storedProc,ID));
public CmsXmlParser getParsedRecord(){
if(parsedRecord == null){
parsedRecord = new CmsXmlParser(getCMSRecord());
return parsedRecord;
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException{
res.setContentType("text/html");
//res.setHeader("Welcome to Directional Project", null);
PrintWriter out = res.getWriter();
getParameters(req);
out.println("<LEFT><H2><FONT COLOR=GREEN SIZE=3>" + getParsedRecord().getCMSRecordHeader() + "</FONT></H2></LEFT>");
out.println("<HTML>");
out.println("<HEAD>");
out.println("<TITLE> Bidirectional Project </TITLE>");
out.println("</HEAD>");
out.println("<LEFT><H2><FONT COLOR=GREEN SIZE=3>" + getParsedRecord().getCMSRecordHeader() + "</FONT></H2></LEFT>");
out.println("</HTML>");
out.close();
//get the parameters to for the email to be sent to the given address
private void getParameters(HttpServletRequest req) throws ServletException, IOException {
this.storedProc = req.getParameter("optProName");
this.ID = req.getParameter("optCustID");
null

U can use doPost() simply call the doGet() in the doPost() as follow...
Let me know if u still have problem...
public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException{
doGet(req, res);
null

Obtaining client certificate in servlet using apache + tomcat

Hi,
I'm porting a webapplication from Javawebserver to Apache/1.3.6 (Win32) mod_jk mod_ssl/2.2.6 OpenSSL/0.9.2b
The application needs to get the client certificate hash code.
Using Javawebserver I used
request.getAttribute ("javax.net.ssl.cipher_suite");
request.getAttribute("javax.net.ssl.peer_certificates");
etc
How do I set up the apache webserver so that I can read the client certificate and what is the attribute called?
I've tried this in the httpd.conf:
SSLOptions +ExportCertData
And the attribute:
"SSL_CLIENT_CERT"
Like it says in the Tomcat documentation.
I'm not sure if I need to set up Tomcat as well..
Any help would be greatly appriciated!
Sincerely,
AM Hjemaas

Yup use ajp13 not ajp12 or mod_webapp
refer to http://www.galatea.com/flashguides/apache-tomcat-24-win32.xml on setting up..
THIS IS IMPORTANT!!!
use Apache mod_jk.dll diretive:
JkEnvVar Apache_Env_Var FORWARD_ALIAS
this will send a apache environment variable (http://myapache/cgi-bin/printenv.pl to see whats available) to Tomcat
JkEnvVar SSL_CLIENT_CERT SSL_CLIENT_CERT
Then in Tomcat servlet use request.getAttribute("SSL_CLIENT_CERT") to get the cert in PEM format
Hope this helps
Jay
